Since all you boys and girls watch Star Trek: "Physicists Nicolae Nicorovici from the University of Sydney, Australia, and Graeme Milton, from the University of Utah, have proposed that devices called superlenses could be used to create a type of cloaking device. Using a principle called 'anomalous localized resonance', superlenses placed very close to a small object could mask its reflected light waves by resonating at the same frequency, much like how noise-canceling headphones mask sound waves by creating a sound that is at the same frequency but inverted in phase."

Phase cancellation can only be accomplished at a single frequency and there can be no variations in transmission through lenses( ie, phase shift distortion, aberration, and impurities). Not a good prospect for "cloaking" anything!
